Definitions

  • rhein of particularly of diacetylrhein are drugs endowed with a relevant antiarthrosic, analgesic and anti-inflammatory activity (Italian Patent No. 1098332).
  • the present invention relates to a number of formulations for oral use with slow release of dyacetylrhein and other derivatives of rhein for therapeutical purposes.
  • the present invention relate to the preparation of rhein derivatives and particularly of dyacetylrhein derivatives in pharmaceutical formulations which permit a gradual and programmed release of the drug and such as to ensure a pharmacologically active hematic level throughout the period of 24 hours from the administration of the therapeutical dose of the drug.
  • Some examples of formulation of rhein derivatives with slow release of the drug are hereinafter described, which have been controlled by the in vitro release test as well as by determining the hematic levels of the drug after experimental administration to animals.
  • 500 g of dyacetylrhein with granule size of between 50 and 100 ⁇ m are carefully admixed with 150 g of finely powdered saccharose and 150 g of Magnolia starch; the mixture is finely ground and then supported onto 1000 g of micronuclei having about 0.4 mm of diameter by wetting with a solution containing 37.5 of polyvinylpyrrolidone.
  • the granulate is dried in an hot air oven, the dried granulate is sieved to prepare end granules of uniform size which are, in portions, coated in a basin with a 20% polyvinil pyrrolidone and 30% shellac solution isopropanol.
  • the number of applications of the coating solution onto the several portion of the granules is adjusted as a function of the release times as experimentally measured by means of the in vitro test.
  • the granules with different coating degrees are admixed as a function of the related release times measured so as to obtain in the same posologic unit (for example a capsule of hard gelatin) the desired amount of drug (for example 100 mg) and the release of the active principle within the programmed times (for instance 24 hours).
  • the desired amount of drug for example 100 mg
  • the desired amount of drug for example 100 mg
  • the release of the active principle within the programmed times (for instance 24 hours).
  • dipropionylrhein 150g are uniformly admixed with 300 g of lactose, 5 g of dispersed slicon dioxide ,15 g of magnesium stearate, 20 g of talc. Separately 350 g of dipropionylrhein are carefully admixed with 350 g of titanium dioxide, 115 g of polyvinylpy rrolidone and 25 g of triacetin. This mixture is wetted until a granulate is obtained which is dried in an hot air oven, The granules are coated in portions into a basin with an acetone solution of cellulose acetophtalate by adjusting the number of applications as a function of the release time to be obtained.
  • the mixture of the powders and the granulates with different coating degree are in turn admixed as a function of the related release times as determined in the in vitro test so as to obtain in the same posologic unit (for instance gelatin capsules, tablets, granulates, etc.) the desired amount of drug and the release of the active principle within the programmed time.
  • posologic unit for instance gelatin capsules, tablets, granulates, etc.
  • diacetylrhein 500 g of diacetylrhein are carefully admixed with 10 g of polyvinylpyrrolidone, 50 g of microcrystalline cellulose , 100 g of sodium citrate; the mixture is wet granulated with water and the granulate is dried in a hot air oven.
  • soya polisaccharides 10 g of talc and 150 g of magnesium stearate are admixed and the mixture is wet granulated and dried.
  • the two combined granulates are converted into tablets by means of a pressing machine and resulting tablets are coated by subsequent application of ethanol solution containing 40g of hydroxypropyl-methylcellulose, phtalate, 10 g of acetylated monoglyceride and 10 g of titanium dioxide.
  • the capsules obtained according to examples 1 and 3 are tested by means of an in vitro release test according to the method reported in U.S.P. XXI.
  • the diacetylrhein has been administered in the two pharmaceutical forms according to a "cross-over" experimental scheme at the dose of 20 ml/kg and with a washout time of a week.
  • the blood sampling has been carried out at the time 0 (basal) and after 1, 2, 4, 8, 12, 16, 20 and 20 hours after the treatment.
